In ages past, the Four Dark Night Venerables stood shoulder to shoulder, guarding the Abyssal Turbid Ancestral Qi. Cang Ye could not bear to let his companions sacrifice themselves. He turned on the other three, seized their origins, and took the light for himself, then personally sealed away his dearest friend. As You Si was sealed, she said only, "I trust you. But remember to come back."
Ages later, Gu Mingguang, an ordinary cultivator from Qingshi Town, unexpectedly inherited the Immortal Light Physique, unaware that he was the "traitor" from his previous life. The Three Dark Night Venerables are about to break free, the peerless Dao cultivator Xuan Chenzi covets his immortal embryo, and the Abyssal Turbid Ancestral Qi stirs restlessly.
Reclaim the origins, and his companions will be annihilated. Set them free, and the mortal world will become a living hell.
He will choose neither. He will take a third path, one that leads to certain death.
The human world has its own Dao, and people can save themselves. So long as the people refuse to sink into ruin, the human world will never lose its light!
